3D CAD Tips: CREO 2.0 IS NEAR


PTC will be talking a lot more about Creo 2.0 in the very near future. For now, what I can say is this: It looks good so far.”

The Tools Used in Conceptual Design


These tools should be intuitive and capable of quickly creating realistic models that can be shared and evaluated by others on the design team. These tools must also be flexible, so designs—still fluid and changeable—can be iterated on and recreated quickly based on design input.

Often as a result of this laundry list of requirements—which are quite different from those of an engineer’s CAD software used for more detailed engineering design—manufacturers end up using myriad of concept design tools from multiple vendors that offer little integration with downstream applications.  As a result, these concepts models must often be recreated in engineers’ CAD program, often losing design intent in the process.

Use of Multiple Tools Multiplies Downstream Issues

In a recent study entitled, Trends in Concept Design, conducted by PTC, the majority of participants (51%) said that they capture design concepts and ideas electronically in the form of 3D data. So what software tools are being used during this exploratory phase of design? The lion’s share of participants in the PTC survey (61%) responded that they use 3D CAD modeling and surfacing tools to quickly create a multitude of potential product designs. Based on the survey results, manufacturers use many different tools during this phase of development.

The use of multiple tools from multiple vendors often complicates the process of concept design and creates problems downstream when concept models move to detailed design.  According to the PTC survey, participants who reported that they used tools from multiple software vendors during the concept phase of new product development were three to seven times more likely to have to recreate data due to incompatibility.

According to the survey respondents, companies using design tools from two vendors were three times more likely to have to recreate data later in the design cycle, compared to those using tools from a single vendor. Those using tools from five different vendors were seven times more likely to have to recreate data, than those buying tools from just one vendor.

One way to avoid these issues is to choose a suite of design tools that is capable of handling all phases of design from concept to detailed design through manufacturing. These tools offer bi-directional interoperability, reducing the risk of miscommunication and eliminating the need for engineers to reinterpret or re-create designers’ conceptual models, safeguarding design intent and facilitating the re-use of design data so mechanical engineers are not starting from scratch once concept models are approved.

Standardizing on one suite of design tools can facilitate brainstorming, manage the exploration of ideas, and aid in the development of product concepts within a single environment. By integrating all these efforts into the same software platform, product concept data is managed in a single, cross-disciplinary data repository, which enables team members to access the information in a timely, secure manner. In addition, customers—through the use of intuitive modeling tools—can collaborate and provide feedback to ensure that concepts will ultimately meet their requirements.

When conceptual design tools and MCAD tools have interoperability with each other, the fruits of designers’ labor—sketches, drawings, and 3D concept models—can be seamlessly brought into engineers’ CAD software where they can get to work further refining the model into a true 3D digital model or virtual prototype that can be ultimately designed, tested, and built.

Connecting the Silos of Design: the use of Integrated CAM and Industrial Design Apps


As a result, the role of design has taken on a much higher priority and become a critical part of business success today. In order to design better products and get them to market faster, manufacturers are increasingly turning to fully integrated apps that connect the various disciplines involved in the design and manufacture of products.

Integration Removes Barriers Between Designers and Engineers

Since the advent of 3D design tools, industrial designers tasked with the look of a new product often found themselves at odds with engineers who’s primary concern was the functional aspects of a proposed design. Industrial designers often find that they must answer to the business side of manufacturing company, who clamor to “see” what the next generation of a product might look like; long before actual CAD work has been initiated.

As a result, designers prefer flexible visualization and conceptual design tools that enable them to quickly flush out a multitude of early concepts of new product designs without concern for the more pragmatic, mechanical aspects of design.

The problem is that this conceptual design stage often becomes an isolated silo within the overall design process, and data created with these conceptual tools is often not used downstream when the actual mechanical design begins.

Manufacturers must understand that designers need a different type of tool, one with a much greater emphasis on the speed required to quickly create multiple concepts, while also having an intuitive interface that requires minimum training. These tools must also be able to create high-quality visualizations long before any actual product geometry exists so the designer can share, discuss, and debate proposed ideas with engineers, cost estimators, manufacturing personnel, and sales and marketing personnel to fuel design collaboration and obtain buy-in on proposed designs.

Since designers and engineers often are tasked with different objectives and use different tools, communication gaps often exist. When engineers recreate conceptual models in their CAD systems, designs often change dramatically. This disconnect between the design/styling team and the rest of the product development team often leads to loss of design intent as designs progress through the design cycle.

Choosing a conceptual design app that is tightly integrated with the CAD system and offers bi-directional interoperability can greatly reduce the risk of this communication gap. It also eliminates the need for engineers to reinterpret or re-create designers’ conceptual models, safeguarding design intent and facilitating the re-use of design data, which shaves off significant design cycle time and reduces the chance of errors.

When conceptual design tools and MCAD tools have interoperability with each other, mechanical engineers can simply bring approved 3D concept models into their CAD software, safeguarding the original design intent and speeding the creation and refinement of the model into a true digital model or virtual prototype that can be ultimately designed, tested, and built.

Tearing down the Walls Between Design and Manufacture

Computer-aided manufacturing has benefitted from CAD integration. Integrating CAD and CAM enables product designers and manufacturing personnel to work collaboratively and removes the interoperability barrier that has traditionally divided the two.  Integrated CAD/CAM tools share the same underlying database so no data translation is required between systems, eliminating the chance of missing, corrupt or unsupported geometric entities, dimensions or notes.

With a fully integrated CAD/CAM environment, all machining calculations are defined, calculated and verified in the same CAD system. Geometries used for machining are fully associative so when changes are made to the CAD geometry, the integrated software automatically updates the corresponding CAM programming. All the data including CAD, toolpaths, fixtures, and tool library are stored in the CAD model, so there are fewer files to track or update when revision changes occur.

Perhaps the biggest benefit of integrated design apps is that is provides a common platform for designers, engineers and manufacturing personnel through which to collaboratively design and manufacture products through improved communication and lowered costs.
